liquid is lie-be distributed in lie form of e but Where l10n-circular :wens are lo be 1103 spray. i sprayed, l form the generally emezive baille .ll/ly spraying device delivers liquid infzlie 'fece in such a manner that at certain point' the annular ward at a sharper or steeper angle than at others, thus giving to the liquid issuing from each such point a trajectory of suiiivcient angular' elevation to enable the liquid to reach the more remote portions of the surface to be sprinkled. It is desirable oi' l course vthat the edge of the nozzle shell or shown more or less .in spraying circular conduit conforml approximately in outline of the curvature. of the baille face.

In the accompanying drawings I have tain embodiments o'apparatus elements of which the Apresent invention is capable.

` In this showing, Figure l is a vertical section ot a-receptacle provided with the delivery or spray device, and suitable for use areas; Fig. 2 is a sectional elevation on a larger scale of a modiied type of nozzle, the section being taken on ,the line II--II of Fig. 3. Fig.l 3 isa plan of the spraying heady shown in Fig. 2.

Referring to Figi l ofl the drawings, l is a conduit leading from any suitable source of liquid supply, (not shown) which is best of an intermittently operating type, and

passing through cover 2 of receptacle 3 hav ing rounded bottom 4 provided with an orifice forming a liquid outlet vat substantially 'its lowest point. A short outlet conduit or shell 5 leads fromthe outlet, and in the present instance is shownas a iiange intcgral with the receptacle, formed adjacent the outlet and projecting therebeyond. v A mushroom-shaped spraying head G having a c'oncaved upper baille surface forms an annular discharge passage 7 with theedges oi the outlet conduit. Suitable centering means, as ribs 8, serve to guide supporting.

rod 9 which is secured to the spraying head. and passes through the outlet conduit to the upper part of the receptacle. The upper end of t-he rod is best threaded, and the rod with the attached spraying head is secured tothe receptacle cover by means of nuts l0 and yll which permit longitudinal adjustment'oil the rod to vary the vertical Width oi' the annular discharge passage,

In Figs. 2 and 3 is shown a modiiied type oi nozzle for spraying non-circular areas where the eii'ective sprinkling rano'e of the nozzle must be greater in some directions .than in others in order, to reach the more remote portions of the area to be covered.

'lhe particular modification illustrated is adapted for use in square washing towers, but the changes necessary to adapt it to towers oi other cross-sections are obvious. rlhat portion of Vchannel 7 shown at the right in Fig. 2 has the same angular direction as in Fig. Il,y the curvature ofthe baille face at 12 being substantially as bei'ore. At y7 however, the discharge channel is shown as extending upward at a steeper angle, the portions 13 of the baille suutace be- `discharge channel slopes updiagrammatically cer-- ing curved upward more sharply than the remainder of the surface, thus increasing the angle of elevation of discharge at these points.

The operation of the sprinkler is Sulliciently clear from the foregoing description. In practice, receptacle 3 should be fed by an intermittently acting source of liquid supply in such av manner that the head of liquid on the nozzle alternately rises and falls. In this way the bell of sprayed liquid issuing from the nozzle, indicated by the curved dotted lines in Fig. l alternately expands and contracts, insuring the uniform sprinkling of` the surface in question. The thickness of-the liquid sheet leaving the nozzle is easily regulated by adjusting the regulating nuts 10 andl 11 to move therspraying head relativelyto the outlet conduit and thus vary the vertical width 0f the ami/ular discharge channel.

lV hat I claim is l. In a liquid-distributing device, a con- .tainer adapted to hold liquid and provided with a discharge oriiice, a baille member p0- ,sitioned outside of said container adjacent said oriiice and having an inner surface curved eoncavely relative to the edge of said oriiice to form therewith a Walled annular dischargev channel extending substantially to the outer edge of'said inner surface, rportions of said channel sloping upwfa-rd radially at a stee er anOle than the remainder otthe channe in order to secure diii'erent effective angles of discharge at `diiferent pointsl on the periphery of said baille member, and means for adjustably securing'said baille member at varying distances from the edge of said orice.

In a liquid-distributing device, a receptacle for liquids having a discharge oriiice in the lower part thereof, a conduit extending fi'oin said orifice and forming the shell of a spraying-nozzle, a spraying head having a concavely curved upper surface conforming approximately in'outline ,with the edges oi' said'eonduit and forming therewith a walled annular discharge channel,

-portions of said channel slpingupward radially at a steeper angle than the remainder oi' the channel in order to secure diil'erent eifective angles of discharge at diil'erent points on the periphery of said sprayinghead, a rod attached to said spraying head and passing through said oriiice, and means in the upper part of said receptacle for adjustably securing said rod and said spraying head in position.
